Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
RollerCoaster Tycoon

RollerCoaster Tycoon
Guest spawns and breakdowns barely matter
Zeus: Master of Olympus
Monster attacks and god visits semi-random
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
